CAS 140-10-3 Cinnamic Acid Powder
What is Cinnamic Acid?
Cinnamic acid is an aromatic organic acid with distinctive bioactivity, characterized by a chemical structure in which a benzene ring is conjugated with a propenoic acid group. This compound, known for its characteristic cinnamon aroma, is primarily biosynthesized in nature via the phenylalanine deamination pathway and is widely found in various plant tissues such as cinnamon bark and benzoin resin. Its unique structural features not only define its physicochemical properties but also confer diverse biological activities, including notable antibacterial and antioxidant effects. As a plant secondary metabolite, cinnamic acid plays a crucial role in plant defense systems and the synthesis of aromatic compounds. It has also become a valuable natural ingredient in the pharmaceutical, food, and cosmetic industries.
